Point is, though, that he had a big blob of water there in the weightless International Space Station and he stuck an Alka-Seltzer tablet, a fizzy tablet in it.

And the bubbles form, but they don't go up.

Instead, they just go around.

They just expand.

They just expand.

So on the International Space Station, a can of carbonated liquid will expand and it'll be like a kind of a foamy mess.

But it's going to all come out as that pressure change causes the gas to come out of solution and now expand.

It's going to be probably quite quick.

I don't know if they've actually done this.

I haven't seen if they've done it on the ISS.

It would make a mess.

I think it would be like if you'd shaken it up and opened it.

Yeah, it makes you thankful for gravity keeping things down.

Wow.

Can it be in the future?

He hasn't stipulated, so I think you can do whatever you like.

I think there's so many cool historical eras of science.

But I feel like I'd be there and I'd be a little bit like, we've moved past this.

But also, I can't really explain to you how we did.

So I'm of no use.
